The system consists of a portal with a self-sealing silicone septum
(accessible by percutaneous needle puncture), a single-lumen silicone catheter, a hemostasis sleeve assembly, and a 3 French micro-catheter assembly which is placed in the hepatic artery using an angiographic placement procedure.
Chemists can simply punch in reaction temperatures on the keypad, watch their reactions proceed through the glass walls of their reaction vessels, and add reagents to reactions in progress through silicone septum
caps that preserve the reaction environment.
The portal consists of a lightweight plastic exterior and interior for patient comfort, a silicone septum
designed to hold a needle in place and allow stable needle retention, and pierceable suture holes(a) designed for easy port removal.
